What is liver somatic index?

The liver somatic index (LSI) is a ratio used to assess the health and condition of an organism's liver relative to its overall body size. It is calculated by dividing the weight of the liver by the total body weight, often multiplied by a constant for standardization. This index can help indicate metabolic or physiological changes in response to environmental factors, diseases, or nutritional status. A higher LSI may suggest liver hypertrophy, while a lower LSI might indicate liver atrophy or dysfunction.
